Rau hluav taws xob cua sov melting, cov tub ntxhais ntawm carburizing thev naus laus zis yog siv cov neeg ua haujlwm zoo carburizing. Kev xa mus rau cov ntaub ntawv cuam tshuam, nws tau txiav txim siab tias cov khoom siv carburizer xaiv yuav tsum muaj cov yam ntxwv hauv qab no.
(1) Tsuas yog tom qab kho qhov kub thiab txias, cov pa roj carbon atoms tuaj yeem hloov pauv los ntawm kev tsis sib haum rau cov ntawv, thiab cov nplaim hluav taws tuaj yeem dhau los ua cov tub ntxhais zoo tshaj plaws ntawm graphite nucleation thiab txhawb kev ua graphitization.
(2) Cov ntsiab lus leej faj ntawm cov carburizers zoo yog qhov tsawg heev, WS tsawg dua 0.03% yog qhov ntsuas tseem ceeb.
(3) Qhov porosity ntawm carburizer kuj tseem ceeb heev rau cov txiaj ntsig carburizing thiab qhov nqus ntawm carburizer. Yog li, cov txiaj ntsig carburizing ntawm qhov kub kub graphitized roj av coke zoo dua li ntawm cov graphite electrode.
(4) Vim tias qhov ntsuas kub qis dua, cov ntsiab lus sulfur ntawm calcined roj av coke carburizer siab dua li ntawm graphitized carburizer, feem ntau tsawg dua 1%, uas tuaj yeem siv rau hauv kev tsim qee cov hlau cam khwb cia hlau.
(5) Calcined thee carburizer tau txais los ntawm calcining zoo anthracite hauv calciner ntawm 1200-1300 ℃. Cov xim dub, cov xim ci ci, cov pa roj carbon 85-93. Cov ntsiab lus ntawm leej faj thiab nitrogen yog qhov nruab nrab
